cZZ- whom it may concern: v 4 Be it known that we, TRAVIS OAKES an ll1m. Rnssinn, citizens of the United St es, both residing at MountVernon, 1n the county of Knox and State of Ohio, have invented certainnew and useful Improvements in Glass Drawing Apparatus, of which thefollowing is a specification. The invention relatesto glass drawingaplifting and lowering'means for'mov- 1112 Ri ht from. the bait isdispensed w embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a diagrammatic front View. of

g the drawing apparatus with our improvemei ed thereto,

2 is a side elevation of the as shown in Figure 1,

igure 3 an enlarged detail side elevasecticn of the connecting de ourinvention. particularly. re-

appation partly in wherein v Figure 4 is a plan view of the device asustrated in Figure 3, and a Figure 5 is a section on the line V-V ofFigure 4.

Referring first to the general arrangement as illustrated in 'Figures 1and 2; 1 is the body of glass from which the drawing takes place; 2 is acylinder in process of drawing; 3 is the bait provided withthe hollowhandle 4 by means of which air under pressure is supplied to thecylinder during 1 drawing; 5 is the carriage to is detachably secured bymeans of the projecting fork 6 passing beneath a collar 7 upon thehandle of the bait; 8,8 are the guides upon which the carriage moves; 9is the connection whereby air is supplied to the hollow handle; 10 isthe pipe leading to the said connection; 11 is a cylinder to which ill 'the pipe 10 is connected; and 12 is the pipe for supplying air tothecylinder 11.

'Iteierring par-stirs and particularly to the connectingbait commonlyemployed in the drawrrangementwherein the use of. inde-' the airconnection to secure disengage 1th. Onewhich the bait now to'Figs. 3, 4and 5 wherein the connection is illustrated in detail, 13 is the elbowto which the pipe 10 is connected; 14, 15, 16, and 17 are connectingmembers 'whereby the elbow 13 is connected to a T 19, and 20 a pipeslidably mounted in the T 19. This pipe20 is provided at its end withacap 21 and carries at its other end the elbow 22 having a flaredopening at its lower end for receiving the rounded or beveled upper endof the bail-.4 as indicated in Fi ure ,3. The pipe 20 communicates withthe by means of the hole 24 and slot 25 (Figure '5). The screwconnection between the pipe 16 and elbow 15 is sufficiently loose topermit of their relative rotative movement, as is also the connectionbetween the pipe 17 and T19, so that the pipe '20 carried b the T13 mayoscillate vertically as anaxis, or laterally with the pi e 17 as an axisand may be slid longitudinally, thus adapting the connection to fit anyposition oft 1e handle 4.

When it is de low handle 4 from the elbow 22, all that'is' necessary-isto move the handle laterally. The elbow 22 is readily cammed upward byward movement is possible by reason of the rotative connection betweenthe pipe lfland elbow 15. The contact between theelbow 22' and the u 7per end of the handle 4 is ordinarily su iciently tight for allpracticalpurposes as the air pressure employed in the apparatus is low. Theoperation is a-c0!ivenient and advantageous one for the reason that inthe .ordinary handling of the cylinders after drawing, it is necessaryto move the apparatus laterally away from y the drawing mechanism, sothat the normal'manipulation of the apparatus is all that is necessaryin order to free the handle of the bait from its connection with the airsupply device. The construction is-also advantageous in that it permitsthe mounting of the connection -directlyupon the drawing carriag'e, andno movement of the connection is necessary in or from the handle.

to provide means for supplying construction will be apparent to thoseskilled in the art.

with the pipe 16 siredto disconnect the holthe rounded end of thehandle, which upbodily with respect to the drawing carriage and providedwith an end having a cam engagement with the end of the hollow handle soarranged that the movement of the handle laterally without tiltingsecures release of the said end from the said member.

2. In glass drawing apparatus, the combination with a bait having ahollow handle, of a member for supplying air to the handle mounted forlateral and vertical oscillation and havingan outlet adapted to makedetachable cam engagement with the end of the hollow handle, whereby alateral movement of the handle automatically disengages it from the saidmember.

3. In glass drawing apparatus, the combination with thebait having ahollow handle, of an air connecting means comprising a support mountedfor universal movement, and a pipe slidably mounted in the support andprovided with an outlet adapted to make detachable engagement with theend of the hollow handle.

4. In glass drawing apparatus, the combination with the bait having ahollow hanedle, with its end beveled, of a laterally ex "tending pipefor su )plying air to the handle pivote at one on for verticaloscillation and having a downwardly opening outlet portion at its otherend formed to fit the beveled end of the handle, whereby the handle andconnection may be automatically disengaged by a relative lateralmovement while the handle is maintained in a vertical position.

5.- In glass drawing apparatus, the combination with the bait having ahollow handle, with its end rounded, of a laterally extending pipe forsupplying air to the handle mounted for universal movement and having anoutlet portion formed to fit theroundedend oi the handle, whereby thehandle and connection, may be automatically disengaged by a relativelateral movement while the handle is maintained in a vertical position.

6. In combination in a glass drawing apparatus, a bait having a hollowhandle, a carriage for lifting the bait, and means whereby air may be.supplied. to the handle comprising, a support, a laterally extendingpipe thereon having one end turned down and fitting over the end of thehandle of the bait, and pivoted on the support for vertical movement ata point removed from the said down-turned end.

7. In combination in a glass drawing apparatus, a bait having a hollowhandle, a carriage for lifting ihe bait and means whereby air may besupplied to the handle comprising a support, a laterally extending pipeslida ble thereon and having one end turned down and fitting over theend of the handle of the bait and pivoted on the support for 'verticalmorement at a point removed i'rom the said down-turned end.

8. In ('omhinulimi in a glass drawing apparatus, a bait having a hollowhandle, a carriage for lifting the bait, and means whereby air may hesupplied to the handle comprising. a support, a laterally extending pipethereon having one end turned down and fitting over the end of thehandle of the bait, and supported for universal oscillatory
